So they can negligent and let them roam free? Which is illegal in most jurisdictions regardless?

No, it's not. It has in fact been explicitly legal for cats to roam free everywhere in the UK since 1971.

Please cite your source for the regulations of 'most jurisdictions'.

Insects don’t care about a bell for one thing, and we already established that it’s not just birds, but insects and vermin the decimate populations of too….

Insects do in fact have senses of hearing, and we've already established that killing rodents is not a problem.

So, one thing people like you who just decry people trying to educate others about the issues, is they also carry deadly diseases and crap everywhere. If they shit in a garden (which they do it’s giant litter box) they can contaminate that persons food.

Lmfao, wash your fucking vegetables. Squirrels, groundhogs, racoons, bugs, and other nature exists in your garden too.

So now that you are educated on the fact that there’s more than just “birds” that are the issue here, your gonna shut the fuck up or at the very least stop insulting people who are more educated than yourself…? Right…?

Says the guy spreading factually incorrect information about the UK's laws around cats in a thread about the UK's laws around cats?

Maybe you should educate yourself before trying to educate others.
